Clutch life
I had 177K on the original clutch in my first car, an '85 accord, and I was the 3rd teenage driver on that car.
I've seen M5 clutches go at 25,000 miles, its really a crapshoot.
Also important is the type of driving - city driving is much more trying for clutches, for obvious reasons. If you drive high mileages on the highway, chances are your car will never need a new clutch. Too bad there's not "clutch pedal maneuver counter" - that would be one way of getting a handle on how rough the car's life has been. A proxy for this is to examine, on an older car (say 1-2 years) the amount of wear on the clutch pedal rubber. I digress.
The one wild card is the possibility of the rear main oil seal failing, or the front gearbox oil seal - oil on a clutch will destroy it in no time. Such failures of seals are rare these days.
My Peugeot 405 has 162,000 miles on its original clutch, and it's not been subject to particularly easy driving. It has, however, never been abused by me. It should be good for another 100,000 miles, I'd guess (just like the car itself should be).
So, expect no clutch troubles for 15+ years if you're a careful driver.
